Pallet Stacker Manufacturers

What manufacturing process is used for the key components of the pallet stacker (such as columns, guide rails, motors, etc.)? How to ensure the accuracy and dimensional stability of the components during the manufacturing process?

Manufacturing process of key components of pallet stackers
The manufacturing process of the columns of pallet stackers is crucial as they support the weight of the entire equipment and achieve vertical lifting. HECHA uses high-precision CNC cutting and welding technology to ensure accurate cutting and seamless welding of column materials. First, high-strength, low-alloy steel is selected as the basic material for the columns. These materials undergo rigorous chemical composition analysis and mechanical property testing to ensure that they meet the requirements of high strength, high toughness and good fatigue resistance. Subsequently, advanced laser cutting technology is used to ensure the precise forming of the column cross section, reduce material waste, and improve processing efficiency. During the welding process, an automatic welding robot is used, combined with inert gas shielded welding (such as argon arc welding), which effectively avoids welding deformation, ensures the straightness and verticality of the columns, and lays a solid foundation for subsequent assembly accuracy.
The guide rail is one of the core components for the pallet stacker to achieve precise positioning and smooth operation. HECHA uses precision cold drawing technology combined with heat treatment to manufacture guide rails. Cold drawing can shape steel with high precision at room temperature, reduce residual stress inside the material, and improve the dimensional accuracy and surface finish of the guide rails. Afterwards, the guide rails are precision ground and polished to further improve their surface quality and reduce friction resistance and noise during operation. In addition, the guide rail material undergoes specific heat treatment processes, such as quenching and tempering, to enhance its hardness and wear resistance, extend its service life, and ensure long-term operation stability.
As the power source of the pallet stacker, the performance of the motor directly affects the operating efficiency and energy consumption of the equipment. HECHA selects efficient and energy-saving permanent magnet synchronous motors and uses advanced manufacturing processes for production. The motor stator and rotor are precision cast and machined to ensure the matching accuracy between the components. At the same time, advanced winding technology and insulation treatment are used to improve the electrical performance and thermal stability of the motor. In addition, the motor must undergo strict dynamic balancing tests during the production process to ensure its stability at high speeds, reduce vibration and noise, and improve the overall operating quality of the equipment.
Measures to ensure component accuracy and dimensional stability
HECHA has a complete testing and quality control system. From the entry of raw materials to the delivery of finished products, each step is strictly inspected and tested. The company has introduced internationally advanced testing equipment, such as three-coordinate measuring machines, laser rangefinders, etc., to perform high-precision measurements on the dimensional accuracy and form and position tolerances of key components to ensure that each product meets the design requirements. In addition, the company has established a strict quality traceability system that can trace back to every production link to promptly discover and correct potential quality problems.
After the key components are manufactured, HECHA uses precision assembly technology, combined with advanced assembly processes and fixtures to ensure accurate matching and positioning between components. During the assembly process, high-precision tools such as laser centering instruments and torque wrenches are used to strictly control assembly accuracy and preload to ensure the overall performance of the equipment. After assembly is completed, the whole machine needs to be debugged, including functional testing, load testing, and operating stability testing, to ensure that the pallet stacker can perform at its best in actual applications.
HECHA is well aware that technological innovation is the soul of corporate development. Therefore, in the design and manufacturing process of pallet stackers, it continuously invests resources in technological research and innovation. The company has a research and development team composed of senior engineers and technical experts, dedicated to the development of new materials, the application of new processes and the research and development of intelligent control systems, and continuously improves the technical content and added value of products. In addition, the company also actively cooperates with domestic and foreign universities and scientific research institutions to carry out industry-university-research cooperation and jointly promote the progress and development of logistics equipment technology.
